- vulnerability check backend moved into lib for reuse in pkg_add
- add pkg_install.conf parsing for common configuration of the various
pkg_install components
- fix crashes related to uninitialised PLIST structures
- check explicitly if the required files in pkgdb are present, fixing
issues with ~empty left-over directories
- improve hardlink handling in pkg_create using the libarchive link
resolver
- pkg_delete with -P overwrite now updates the pkgdb correctly
- silence warning about empty /var/db/pkg, it provides no value
- pkg_info uses libfetch for remote locations and works without
temporary files, speeding up operation a lot
